[0028] The utility model makes further illustration in combination with the drawings below.
[0029] As shown in Figure 1 A CCS test tool, comprising a base plate 1, and a positioning adjustment assembly 2, a tool assembly 3, a pushing assembly 4 and a plurality of test assemblies 5 installed on the base plate 1. Wherein, the positioning adjustment assembly 2 comprises an installation support 2-1 and a lifting adjustment assembly 2-2. The installation support 2-1 is installed on the base plate 1 through the lifting adjustment assembly 2-2, and can be lifted or lowered under the drive of the lifting adjustment assembly 2-2. Each test assembly 5 is arranged on the installation support 2-1 in turn, and is slidably connected with the installation support 2-1, and can be adjusted according to the position of the measurement and control point of the CCS to be tested.
[0030] The base plate 1 is provided with two processing stations, respectively a test station below the test assembly 5, and a loading and unloading station away from one side of the test probe 5-2. The tool assembly 3 is slidably connected on the base plate 1, and can be switched between the test station and the loading and unloading station under the drive of the pushing assembly 4, so as to facilitate the workers to clamp the CCS to be tested on the tool assembly 3 or disassemble it from the tool assembly 3 before and after testing.
[0031] The lifting adjustment assembly 2-2 is two in total and symmetrically arranged on the base plate 1. The lifting adjustment assembly 2-2 comprises a top plate, a lifting cylinder and two guide columns. Wherein, the lifting cylinder is fixed on the base plate 1, and the driving end is fixed with the top plate, which can drive the top plate to move up and down. The two ends of the installation support 2-1 are respectively fixed with the top plates in the two lifting adjustment assemblies 2-2, which can move up and down synchronously with the movement of the top plate. The two guide columns are respectively installed at the two ends of the top plate, and are slidably connected with the top plate, which is used to ensure the stability of the top plate during lifting.
[0032] Further, a limiting assembly 6 is arranged below the top plate, which is used to limit the limit position of the top plate. As shown in Figure 2 The limiting assembly 6 comprises a limiting support 6-1, a buffer 6-2 and a limiting rod 6-3. Wherein, the buffer 6-2 and the limiting rod 6-3 are both installed on the top of the limiting support 6-1. The top plate can be buffered by the buffer 6-2 during the descending process, avoiding the descending speed being too fast, so that the damage between the test assembly 5 and the measured CCS occurs. The bottom of the limiting rod 6-3 is fixed on the limiting support 6-1 through screw, which can adjust the limit position of the top plate descending according to the thickness of the measured CCS, avoiding the position of the top plate descending being too low, which leads to the test end of the test assembly 5 inserting into the measured CCS, causing damage to the measured CCS.
[0033] As shown in Figure 3 And 4As shown, the test assembly 5 comprises a probe mounting seat 5-1 and a plurality of test probes 5-2. Among them, the probe mounting seat 5-1 is connected to the mounting bracket 2-1. A plurality of probe sleeves are fixed on the probe mounting seat 5-1. Each probe sleeve is provided with a test hole position matched with the test probe 5-2. The test probe 5-2 is plug-in fixed in the test hole position. The worker can quickly install the test probe 5-2 in the corresponding test hole position according to his own needs.
[0034] Further, the test probe 5-2 and the bottom of the test hole position are provided with a reset spring, which can avoid damage to the test probe 5-2 when it is pressed down.
[0035] In this embodiment, as shown in the figure, Figure 3 The mounting bracket 2-1 comprises two support frames 2-1-1 arranged at intervals. The interval between the two support frames 2-1-1 forms an observation channel 2-1-2, which facilitates the worker to visually observe the test assembly 5. Each support frame 2-1-1 is provided with a sliding groove. The top of the probe mounting seat 5-1 is provided with a fixing piece matched with the sliding groove. The fixing piece passes through the sliding groove, and the bottom is fixed with the probe mounting seat 5-1, realizing the sliding fit between the probe mounting seat 5-1 and the support frame 2-1-1.
[0036] As shown in the figure, Figure 5 The tool assembly 3 comprises a detection table 3-1, two limit pieces and two clamping blocks 3-4. Among them, the detection table 3-1 is provided with a track groove matched with the limit piece. The two limit pieces are slidingly connected in the track groove, sliding along the length direction of the detection table 3-1, and can be locked at any position, realizing the position locking of the measured CCS in the length direction. The two clamping blocks 3-4 are slidingly connected on the detection table 3-1, sliding along the width direction of the detection table 3-1, and can cooperate with the limit piece to lock the position of the measured CCS in the width direction.
[0037] Specifically, the limit piece is L-shaped. The two limit pieces are symmetrically arranged on the detection table 3-1, which are divided into a first limit piece 3-2 and a second limit piece 3-3. Among them, the first limit piece 3-2 is fixed on the corner of the detection table 3-1 by screws. The second limit piece 3-3 is slidingly connected in the track groove and is provided with a locking piece. The bottom of the track groove is provided with a plurality of lock holes matched with the locking piece. When the second limit piece 3-3 slides to the specified position, the position locking of the second limit piece 3-3 can be realized through the cooperation between the locking piece and the lock hole, and then the clamping of the measured CCS is realized.
[0038] Further, the first adjusting through slot is arranged on the second limiting piece 3-3, and the length direction of the first adjusting through slot is the same as the sliding direction of the second limiting piece 3-3. The bottom of the locking piece passes through the adjusting through slot, so that when the second limiting piece 3-3 slides to the position of the measured CCS, the first adjusting through slot can be further adjusted to ensure that the second limiting piece 3-3 can be tightly attached to the measured CCS.
[0039] In the embodiment, the second position giving slot is arranged on the two clamping blocks 3-4, and the length direction of the second position giving slot is the same as the width direction of the detection table 3-1. The fastener is arranged in the second position giving slot. The bottom of the fastener passes through the second position giving slot and is screwed with the detection table 3-1.
[0040] When the position of the measured CCS is limited, the fastener is loosened, so that the stop block can move along the width direction of the welding platform, and the clamping block 3-4 can be tightly attached to the measured CCS. When the clamping block 3-4 moves to the specified position, the clamping block 3-4 is locked by tightening the fastener, and the position of the measured CCS in the width direction is limited.
[0041] In the embodiment, the fixing piece, the locking piece and the fastener are all screws.
[0042] As shown in Figure 1 The pushing assembly 4 includes a pushing cylinder 4-1 and a sliding rail 4-2. The detection table 3-1 is slidably connected to the bottom plate 1 through the sliding rail 4-2. The piston rod of the pushing cylinder 4-1 is connected to the detection table 3-1 through a connecting piece. By extending or retracting the piston rod in the pushing cylinder 4-1, the detection table 3-1 can be switched between the test station and the loading and unloading station.
